USAC in for enduro...

Here is the added rule:

"5E4 - Enduro
An extended timed descent or multiple timed descents in
single or multiple stages over one or more days. A technical
manual should be produced that defines how the event will be
scored, either by time or omnium. All stages must be
completed to be eligible for a placing. "

thoughts?? what about classes?? Is a pro in DH and a pro in XC the same?? USAC only has categories for XC, DH and 4x/DS. They have no plans to add enduro??
